Interesting!
And I am glad they provide an automatic "fireman", because running a steam loco was definitely a 2-person job - - and I want to be the engineer (as well as the brakeman and conductor).
Also glad they left out the handgenade to simulate the experience of the letting the boiler water get too low.
But getting to a water source and adding coal to keep the automatic fireman supplied seems like an effective way to make you think about the steam in "steam engine."
